I have a 1998 Honda Civic LX that is stalling and has a slight vibration issue. The car has 197,000 miles on it and it is an automatic. The car started out hesitating randomly. Then it started doing it more after the car was warmed up, and now it is pretty constant after it gets warmed up. I read a few forums talking about the TPS being the issue. What does everyone think it is TPS or transmission? If you think it is a TPS issue where is it located at and does anyone have any pictures of it?

Thanks for looking and any advice you can give me!!!!

 

Go for it....check the middle wire for voltage. should read .45, WOT should read 4.9.

 

when was the last tuneup?

 

cant hurt to check the tps and this guy made a good write up for it

It has been a while since the last tuneup.

 

The write up looks awsome espicially for a weekend/non mechanic like me.

Thanks!!!!!

 

I checked the voltage with the green wire being ground and the red wire as positive on the TPS. The voltage with key on the run postion and engine off was .43V and with the accelorator pressed it was 4.3V. With the engine on and warmed up at idele the volts were .43V and with car at 6000 RPMs I could not get a reading. Did I do this right and is the TPS bad?

 

I have the same problem, i bought a new TPS and still the same problem, this is annoying
